Jawaban:
Volume kerucut:
1/3 × L. alas × tinggi
1/3 × 22/7 × 49/2 × 49/2 × 72
11 × 7 × 49 × 2
7546 cm³
- Penjelasan dengan langkah-langkah:
- v = 1/3 × l.alas × tinggi
- = 1/3 × [ π × r × r ]× tinggi
- = 1/3 ×[ 3,14 × 24,5 × 24,5 ]× 72
- = 1/3 × 1.884,785 × 72
- 3 coret sama 72 = 24 berarti ↘️
- = 1.884,785 × 24
- = 45.234,84 cm kubik
